Furthermore, at least one through hole 212 is arranged on the flow channel 21, the negative ion generator 29 is arranged near the flow channel 21, the negative ions are connected with the through hole 212 through the release module 214, and the distance from the release tip 210 to the air inlet part 23 is larger than that from the air outlet part 24, so that the moving path of the negative ions in the flow channel 21 is smaller, the consumption of the negative ions combined with dust particles in the air is reduced, and the concentration of the negative ions in the air flowing out of the air purifier is improved.
In a preferred embodiment, in addition to the above, a sealing ring 213 is further disposed on the through hole 212, and the sealing ring 213 is adapted to the through hole 212 and the releasing module 214. The loose connection between the releasing module 214 and the through hole 212 of the flow channel 21 can cause a part of air and negative ions in the flow channel 21 to flow out from the through hole 212, and further, the sealing ring 213 is arranged on the through hole 212, so that the connection between the through hole 212 and the releasing module 214 is tighter, the air and the negative ions cannot flow out from the through hole 212, and the action effect of the flow channel 21 is better.
